General Comments:

These data are from 161Er ε decay, in-beam γ studies, and several charged-particle reaction studies.

Several studies of the 161Er decay scheme reported after 2000 have appeared in which modifications to the level scheme presented here have been reported. Because many of the details regarding these modications have not been given and because they remain as yet unpublished, the evaluator has not included them here. For a discussion of these matters, see the 161Er decay data set.

In 160Gd(7Li,6nγ), 2004Es01 propose the existence of a band structure consisting of both signature partners and tentatively assign it to 161Ho. Because almost nothing is known about this band, the evaluator has not adopted it. For additional information about it, see the (7Li,6nγ) data set.

Levels: Model calculations can be found in the following: wavefunctions of various levels - 1972So12 (or 1971SoZW), 1972WiZG, 1972FuZH, 1992Bo45, and 1995Dz02; B(E1) values between members of the 7/2[404] and 7/2[523] bands up to 17/2 - 1973Ba86; and other theory discussions - 1984Ja10 and 1992Ba42.

Levels: band(a) 7/2[523] GS band, α=+1/2 branch.

Levels: band(b) 1/2[411] band, α=-1/2 branch.

Levels: band(c) 7/2[404] band, α=+1/2 branch.

Levels: band(d) 3/2[411] band, α=+1/2 branch.

Levels: band(e) 1/2[541] band, α=-1/2 branch.

Q-value: Note: Current evaluation has used the following Q record

E(level): From least-squares fit to γ energies where γ transitions occur; otherwise from average of results of reaction studies. For γ’s whose energies are quoted to only the nearest keV, the ΔE values are assumed to be 1 keV. For levels all of whose deexciting γ’s are known to only the nearest keV no uncertainties are given for the level energies.

Jπ(level): Jπ and band assignments are based on the following: ce data from 161Er ε decay studies; γ(θ) from in-beam studies, especially as they imply stretched E2 character of the γ’s; the agreement of measured and calculated cross sections for the charged-particle reactions; and the expected structure of the rotational bands.

Jπ(level): Wave functions from model calculations of 1992Bo45 show >88% of the state corresponds to the Nilsson state listed here for bandheads at 0, 211, 252, 298, 760, and 826 keV. The model results for the bandheads at 423, 446, and 592 keV are listed for those levels.

E(γ): From decay-scheme studies (primarily 1972Ka37 and 1972Wo08) and in-beam studies (primarily 1971Fu08 and 2004Es01). Unplaced γ’s from 161Er ε decay and in-beam studies are not included here. γ’s listed only to the nearest keV are generally from 2004Es01.

I(γ): Average of available data from decay scheme and in-beam studies.

M(γ): Multipolarities are based primarily on relative internal-conversion subshell intensities (1965Gr35) and α(K)exp values (1972Ka37) in 161Er ε decay, and γ(θ) from (α,2nγ) study (1971Fu08). The Q are generally taken to be stretched E2. See the 161Er ε decay and (α,2nγ) for the experimental results.
